...not something I have an issue with, being 150cm tall and female...
But seriously, I don't care. In fact if I met a guy shorter than me (within reason) I would probably ask him out on the spot...although of course you have to account for more delicate things.
What else...erm, I'd prefer someone who wasn't too tall, because they'd make me look ever shorter, and I'd have some issues with the physics of kissing and hugging. Having said that...Hayden Christensen is 185cm. Yummy.
My brother is now 5cm taller than me, and he is twelve, and he has a rather "old" face for his age - he looks fourteen-ish. I on the other hand resemble a twelve-year-old, despite being sixteen. Some of my friends say it looks like I'm dating my brother when I take him places with me. Oh dear.
